The Role of Peroxisome Proliferator-Activated Receptor γ Coactivator-1 β in the Pathogenesis of Fructose-Induced Insulin Resistance

Peroxisome proliferator-activated receptor gamma coactivator-1 beta (PGC-1beta) is known to be a transcriptional coactivator for SREBP-1, the master regulator of hepatic lipogenesis. Here, we evaluated the role of PGC-1beta in the pathogenesis of fructose-induced insulin resistance by using an antisense oligonucletoide (ASO) to knockdown PGC-1beta in liver and adipose tissue. PGC-1beta ASO improved the metabolic phenotype induced by fructose...
